I was dx with congestive heart failure over 20 years ago, have a pacemaker, and a metal mitral valve. At age 89, my biggest problem is fatigue/exhaustion, but Dr. Leshen informed me when I saw him for the first time in October 2019 that "exhaustion is not a symptom of heart failure" and that I am "depressed because I "have no motivation, and that is caused by my depression"; so it is "time to see my primary" (whom I saw 2 weeks ago and told me to talk to HIM about my exhaustion). I am on such strong latex that I cannot even go to church, but still do my own cooking, cleaning, etc. Dr. Leshen suggested that he increase my latex because my primary said my severe leg pain is due to swelling in my ankles. Dr Leshen also said "your heart condition has not changed in 3 years" although NO tests other than lab work and EKGs have been done in that time, none recently. He referred to my pacemaker as a defibrillator, and when I objected he said "well most of my clients have defibrillators".

A very good experience for us. Dr. Leshen is calm, but quick to explain and to act. He went beyond expectation by contacting other out-of-town docs to get details on the patient's prior surgeries so he could plan the best access route before taking him to cath lab. Highly recommend. (We met Dr. Leshen at the hospital, after entering through the emergency room, so have no comment about the office staff, etc. )
